Symptom: Your LCD display inside your instrument cluster is very dim, or was dim before, but now you cannot see anything at all on it. So you are left with only the analog dials (needles) to rely on, for information. This prevents you from accessing settings for the car. This DIY will help you fix this issue. Most of the time, the issue is a transformer located on the main board of cluster, that becomes defective. Remedy is to replace it. Below info will show you every step of the way, from trim removal, taking cluster apart, doing solder rework and putting it all back together.
Pictures are very self explanatory. I just completed this, after collecting information from multiple sources. Collected so that one can do it all from one place. Hope this helps.
Do yourself a favor, review entire DIY before you start, so you know what you will need, what you will need to do, etc.
Ordered from this place for $25.90 plus about 23 bucks for shipping. If you plan to replace both transformers (one for LCD, another for analog dials brightness), order two and replace both.
If you are not sure you can tackle this, get someone that can solder.
